7.3. Overcloud Creation Example

The following command is an example of how to start the Overcloud creation with custom environment files included:
$ openstack overcloud deploy --templates -e /usr/share/openstack-tripleo-heat-templates/environments/network-isolation.yaml -e ~/templates/network-environment.yaml -e ~/templates/storage-environment.yaml --control-scale 3 --compute-scale 3 --ceph-storage-scale 3 --control-flavor control --compute-flavor compute --ceph-storage-flavor ceph-storage --ntp-server pool.ntp.org
This command contains the following additional options:
  • --templates - Creates the Overcloud using the Heat template collection in /usr/share/openstack-tripleo-heat-templates.
  • -e /usr/share/openstack-tripleo-heat-templates/environments/network-isolation.yaml - The -e option adds an additional environment file to the Overcloud deployment. In this case, it is an environment file that initializes network isolation configuration.
  • -e ~/templates/network-environment.yaml - The -e option adds an additional environment file to the Overcloud deployment. In this case, it is the network environment file from Section 6.2.2, “Creating a Network Environment File”.
  • -e ~/templates/storage-environment.yaml - The -e option adds an additional environment file to the Overcloud deployment. In this case, it is a custom environment file that initializes our storage configuration.
  • --control-scale 3 - Scale the Controller nodes to three.
  • --compute-scale 3 - Scale the Compute nodes to three.
  • --ceph-storage-scale 3 - Scale the Ceph Storage nodes to three.
  • --control-flavor control - Use the a specific flavor for the Controller nodes.
  • --compute-flavor compute - Use the a specific flavor for the Compute nodes.
  • --ceph-storage-flavor ceph-storage - Use the a specific flavor for the Ceph Storage nodes.
  • --ntp-server pool.ntp.org - Use an NTP server for time synchronization. This is useful for keeping the Controller node cluster in synchronization.
